Stir the Material
Before printing with all materials, you must mix the material bottle on the NextDent® LC-3DMixer. Before printing again with those materials, you must stir the material in the print tray using the Resin Mixer, as seen in the next section. The chart below describes each compatible material's requirements for: bottle mixing time, stirring time in the print tray, and post-curing time. The curing time is included so the chart may be a quick reference guide for stirring and curing materials. Please read your material's label to be sure whether or not the material requires mixing and stirring.
If material has spilled or dripped down the print-material bottle, clean the bottle with Isopropyl Alcohol (IPA) and paper towels. IPA will clean the material off without ruining the bottle label.
 |
CAUTION: Your material bottle's QR code must be able to be scanned by the printer. Using another solvent besides IPA to clean the bottle risks damaging the QR code. If this happens, call your authorized print-material provider for further guidance. |

WEAR 100% nitrile gloves whenever handling liquid FabPro/NextDent material and/or ipa. |

 |
NOTE: If your print-material bottle has been sitting unused for more than one month, treat it like a new bottle and mix it according to the "brand new bottle" column above. |
|
NOTE: Instead of using the bottle mixer, you may opt to mix the material bottle by hand, shaking it vigorously in an up-and-down motion. Shake it for five minutes for a new material or for one you are treating as new (see above note). Shake the bottle for two minutes for a recently used bottle. Please see the section Begin Your Print Job for more information. You MAY NOT hand-mix NextDent Model 2.0 material. This technique will not sufficiently mix the material. |
|
NOTE: Ensure that you place the build in your UV curing oven in the same orientation it was printed in, as if the bottom of the oven is the print platform. |
Resin Mixer
Material that is left in the print tray between builds needs to be stirred periodically with the Resin Mixer. Refer to the Material Stirring and Curing Chart and/or your material's Instructions for Use for information on stirring print materials.
|
CAUTION: Failure to sufficiently mix materials before each build may result in color deviation and/or print failure. |
 |
CAUTION: Ensure that the mixer is clean before each use. To clean the mixer, wipe it with a nonabrasive cloth and the recommended solvent. |

|
CAUTION: Putting too much pressure on the print-tray film can dent or puncture the film, rendering the tray unusable. The film cannot be replaced by itself; if the film is damaged, the whole print tray must be replaced. |
|
CAUTION: Puncturing the print tray will force a full tray's worth of print material into the catch tray. Use extra caution when handling a full catch tray. |
|
CAUTION: If the print tray gets punctured, discard it in the same way you would other materials that have been in contact with liquid material. |
|
CAUTION: Take care not to slosh material out of the print tray while stirring. If this happens, you will have to clean the parts of the printer that the material got on. |
-
After stirring, allow the mixer to drip material back into the print tray and then wipe excess material off the mixer with a nonabrasive cloth.
- Repeat this process before every print job.
|
CAUTION: Be sure to clean the mixer with IPA between uses. Failure to do so risks mixing unstirred material or different material in with material currently in the print tray. |
